Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will receive either active (ACH-0144471) or placebo.
A total of 46 subjects in four separate dose cohorts are planned. ACH-0144471 will be administered as multiple doses over a 14-day period. The dosing interval will be determined based on emerging data, and there will be flexibility to explore different dosing frequencies. In order to ensure sufficient placebo subjects for comparison at the first dose level, the first dose cohort will include 16 subjects, randomized 1:1 to active drug and placebo; the remaining dose cohorts will enroll 10 subjects per cohort, randomized 4:1 (8 active drug and 2 placebo).

The dose for the first cohort will be determined based on the data from at least 2 doses in the currently ongoing SAD study (ACTRN12616000082404p) (clinical safety, observed PK/PD relationships). The dosing for the next cohort will proceed at a new dose level/regimen, based on the acceptability of available safety and PD results. This procedure will be repeated for all doses in this study. The maximum dose for this study will be calculated so that the predicted Cmax and AUC0-24 do not exceed the NOAELs observed in nonclinical studies, and may be adjusted upward or downward based on emerging nonclinical and clinical safety, PK, and PD data.

All doses of ACH-0144471 or placebo will be administered orally. Dosing should be at the same time each day. All doses should be administered within 5 minutes of the scheduled time.

All dosing is to occur during subject housing optimizing subject compliance.

Treatment: Drugs
Comparator / control treatment
The placebo for ACH-0144471 liquid filled capsules (LFCs) dosage forms will be extemporaneously prepared by the clinical site and/or an alternative approved site. The excipients used in the placebo for ACH-0144471 LFCs will be the same as the excipients used in the active ACH-0144471 LFCs. All excipients will be precedented and have regulatory acceptance. The number of capsules required will be adjusted based on the final doses chosen for each group.
Control group
Placebo

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Study drug components will be shipped to the study center in open-label fashion. An unblinded pharmacist and the associated pharmacy staff at the study site will be responsible for dispensing according to the randomization schedule provided. The unblinded pharmacy staff will affix a blinded, unitdose label to the drug identifying which study subject should receive which dose. All doses will be administered by blinded site staff.

Summary
Brief summary
ACH-0144471 is a new orally (by mouth) administered complement factor D (fD) inhibitor being developed by Achillion Pharmaceuticals, Inc. for the treatment of complement mediated diseases. Many diseases are associated with inefficient control of complement or too much activity of the complement system. This study will help determine the correct dose, whether this medication has any side effects and how effective it is at controlling the complement system.

A total of 46 subjects in four separate dose cohorts are planned. ACH-0144471 will be administered as multiple doses over a 14-day period. The dosing interval will be determined based on emerging data, and there will be flexibility to explore different dosing frequencies. In order to ensure sufficient placebo subjects for comparison at the first dose level, the first dose cohort will include 16 subjects, randomized 1:1 to active drug and placebo; the remaining dose cohorts will enroll 10 subjects per cohort, randomized 4:1 (8 active drug and 2 placebo).
